SIGNORS TO NATIONAL LEAD COME'ANY, 0]? NEW YORK, N. Y., A GORPORATIQN OF NEW YORK.

Application filed May 18,

To all whom it may concern:

Be it known that we, EDWARD C. lVALnnn and FREDERICK J. BRINKER, citizens of the United States, and residing at St. Louis, State of Missouri, have invented the new and useful Improvement in Barrel-Closing Processes and Mechanism, of which the following is a specification.

This invention relates to a process and mechanism for closing barrels and similar containers, and is applied more particularly to the closing of containers constructed of sheet metal and the like.

Such materials as white lead are shipped in metal containers, including metal barrels. These containers must be of strong and rugged construction since the material has considerable Weight and is in fluid or semifluid form. Such containers must also be securely sealed in such a way as to avoid the seal being accidentally broken during the handling of the barrel and by the yielding or distortion thereof.

One of the objects of this invention, therefore, is to provide a method of sealing such barrels and containers which shall provide a tight seal and one securely locked against accidental breaking of the seal.

Another object of this invention is to provide mechanism for effectively sealing such a container. 7

Further objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure 1 is a view showing part of a sealed container with the sealing mechanism in place thereon;

Fig.2 is an enlarged fragmentary view showing the sealing mechanism in the proccss of forming a seal; and

Fig. 3 is a partial plan view of Fig. 1.

Referring to the accompanying drawing, 1. designates the body of the barrel or container, the upper part of which is flared outwardly so as to form a seat 2 for the barrel head. Beyond the seat 2 the metal is formed over a pair of reenforcing strips 3 so as to provide a bead. 4 along the upper rim of the barrel. The barrel head is also formed of sheet metal with a dished body 5 and an rip-turned tapering flange 6 adapted to fit the tapered seat 2 on the barrel. The upper part of the flange 6 is turned outwardly to provide a top flange 7 adapted to rest on the rim of the barrel when the head is in.

place. The tapered flange 6 may be formed to have a snug fit in the seat 2 so that by forcing the head down into said seat until the flange? engages the rim of the barrel a tight seal is provided.

In order to secure the head in place after it has been forced home, a ring 8 is provided having an upper flange 9 adapted to rest upon the flange 7 and shaped to fit the same, and an outer vertical flange 10 adapted to slip over the head 4 on the rim of the barrel. When the ring 8 is first applied the flange 10 is straight as shown in Figure 2. This flange is then curled under the bead 1 as shown in Figure 1.

. In order to turn under the flange 10 as above described the following mechanism maybe provlded. A frame consistingof a horlz'ontally disposed cross-bar 11 and having an up-standing projection 12, is provided with a bearing pin'13 adapted to carry a roll 14 having a concave face 15 adapted to run on the ring 8 when in place on the barrel. The opposite end of the bar 11 is bifurcated having apair of clownwardly extending arms 16% (only one, of

then bent substantially at right angles so'as to provide a horizontally extending manipulating handle 21. Near the bend of the lever a concave roll 22 is carried on a bearing pin 23. The arrangement is such that when the ring 8 has been applied and forced down on the head, the closing l'nechanism may be applied by engaging the rolls'18 under the rim on one side and resting the roll 14 on top of the ring 8. The roll 22 will then be in a position to rest against the extended free edge of the flange 10 as illustrated in Figure 2. By now applying a downward pressure on the end of the arm 21, the operator may turn the flange 10 inwardly under the bead l and by turning the entire mechanism around the barrel head the rolls ll-and 22 roll along the ring 8, the roll 22 turning under the free edge oft-he flange 10 as it progresses. During this nloven ent the rear end of the bar 11 will be guided by the rolls 18 which run around under the rim or bead 4. Vhen the turning in or the flange 10 has been completed, the barrel will have the appearance shown in Figure 1.

Thus a simple and convenientmethod for closing barrels is provided; The barrel end is shaped so as to form a snug taper fit with the barrel head. The locking ring 8 may then be applied over the barrel head and secured to the barrel by crimpingthe flange 10 as described, The mechanism for accomplishing this purpose is re'y siinple'f. The frame 11 is quickly and ea rly applied and rolls on the barrel rim, being guided the rolls f8 and let While the roll 22 etlectiv cly turns under or crimps the fial ige 10 under the bead so as to seeure the'barrel head in place.

It is obvious that arious changes may be made in details of constructionwithoiit dcpartin'girom the spirit oftliis invention-5 it is, therefore, to be understood lthatfthis in vent on s not to be limited to the spec fic detalls shown and described.-
